One pair of glasses costs £30. Another, which looks almost the same, costs £300. Is the expensive pair really ten times better, or are you paying for the name?
The honest answer: some of the difference is real, and some of it isn't. This guide breaks down where the money goes, what's genuinely worth paying for, and how to get great glasses without overspending.
Why are glasses so expensive?
The price of a pair of glasses is made up of three parts:
- The frame: materials, build quality and, for designer frames, the brand name.
- The lenses: the lens type, thickness and any coatings.
- Everything around it: high-street rent, staff, marketing and retailer margins.
The third part is often the biggest. A large share of high-street prices pays for shops and advertising, not for better glasses. Buying online cuts most of it out, which is why the same quality can cost far less.

The key row is vision quality. How well you see depends on the lenses being made accurately to your prescription and fitted correctly, not on the price of the frame.
What's worth paying more for
Some upgrades make a real difference to how your glasses look, feel and last. These are worth the money if they fit your needs:
- Thinner, high-index lenses if your prescription is stronger than about ±4.00. They make your glasses lighter and stop thick edges.
- Anti-glare coating if you drive at night or work under bright lights. It cuts reflections and makes your eyes visible to others.
- Premium varifocal lenses if you need varifocals. Wider reading and screen zones make them much easier to live with. See our varifocal guide.
- Sprung hinges or a sturdier frame if you're tough on your glasses, or for children.
- Accurate fitting. Correct PD and lens positioning matter more than any brand name.
What's not worth paying extra for
- A logo you don't care about. If the brand isn't important to you, a well-made budget frame in the same shape gives you the same look for a fraction of the price.
- High-street mark-ups. You don't need to pay for shop rent to get good glasses.
- Coatings you won't use. A blue light filter isn't essential if you rarely use screens, and you don't need tints for everyday indoor glasses.
- Thin lenses for a mild prescription. Standard lenses are already thin and light for mild prescriptions.
When cheap glasses are the smart choice
Budget glasses aren't just about saving money. They're often the better choice for:
- A spare pair to keep in the car, at work or in a bag
- Reading glasses you'll leave around the house
- Children, who outgrow and break glasses quickly
- Trying a new style without committing to an expensive frame
- A mild prescription where premium lenses add little
Our budget glasses start from just £6, with frames like the Brooklyn DB9951 at £29 and the Dune DUN036 at £49, originally up to £99.
When premium or designer glasses are worth it
- You wear glasses all day, every day, so comfort and durability really matter
- You have a strong prescription and want the lightest, thinnest result
- You want a specific designer look that you'll wear for years
Even then, you don't have to pay full price. Our designer frames from Oakley and Ray-Ban start from around £69, and our affordable designer glasses guide shows you how to get the brand for less.

Cheap vs expensive glasses FAQs
Are cheap glasses bad for your eyes? No. Cheap glasses won't harm your eyes as long as the lenses are made accurately to your prescription and fitted with the correct PD. The frame price has nothing to do with your eye health.
Do expensive glasses give clearer vision? Not automatically. Clear vision comes from accurate lenses and correct fitting. Premium lens options can improve comfort, for example thinner lenses or wider varifocal zones, but a well-made budget pair gives the same sharp vision for a standard prescription.
Why are designer glasses so expensive? You're paying for the brand name, signature design details and often higher-grade materials. Retailer mark-ups add to the cost. Buying designer frames online can cut the price significantly.
How long do cheap glasses last? With care, budget glasses can last a couple of years or more. Keep them in a case, clean them with a microfibre cloth, and take them off with both hands to protect the hinges.
Is it worth buying glasses online? For most people, yes. You get a much wider choice and lower prices. You just need your prescription and PD. Here's how to read your prescription and how to measure your PD.
Great glasses don't have to cost a fortune
The best glasses are the ones that fit your prescription, your face and your life, not the ones with the highest price tag. Spend where it matters, save where it doesn't, and you'll get a pair you love for a lot less.
